RESUMEN
Schwannomas are the fourth most common primary neoplasms affecting the brain and cranial nerves. Central lesions commonly arise from sensory nerve roots, and a common intracranial site is the vestibular branch of the 8th nerve (>85%). We present the case report of a patient who has a schwannoma extending from the pterygopalatine fossa to the orbit, complaining about facial pain in the trajectory of the trigeminal ophthalmic branch. Schwannomas represent 1 to 2% of all neoplasms of the orbit, and trigeminal schwannomas are extremely rare, accounting for less than 0.5% of all intracranial tumors.

We report two cases of trigeminal neuroma that were operated on by the neurosurgery team at Felício Rocho Hospital, Belo Horizonte, Minas Gerais State, Brazil. Endoscopic assisted microsurgery was the technique used to approach the gasserian region tumor with good results.
Descrevemos dois casos de neurinoma do trigêmeo operados no Serviço de Neurocirurgia do Hospital Felício Rocho, Belo Horizonte, Estado de Minas Gerais, Brasil. Utilizamos com sucesso a microcirurgia assistida por endoscopia para abordagem de tumores da porção gasseriana.

This paper reviews and expands the Jefferson's Classification regarding the localization of trigeminal schwannomas. The authors present a series of specific surgical approaches best suited to remove these tumors. Using skull base neurosurgical techniques, the authors present the most direct, efficient and safety surgical approaches to remove each of five different types of trigeminal schwannomas. Three illustrative cases of their own are also presented.
